Hi.
I tend to buy mine from Erevital and use the Biosun Hopi Ear Candles.
Ear candling is a subject which has previously created loads of replies on this site. Personally, they worked for me, and subsequently I trained to use them. They "cured" (yes "cured" eventually) head pressure which a hospital consultant could not help with. However, some people find it hard to understand the benefits. I feel that although some people may have TRIED it, they haven't NEEDED it, and hence can't FEEL the benefit. Each to their own I suppose but I remain totally convinced they work.
However, I don't know with whom you trained but nothing comes out of your ears! I never tell my clients this (even though this may have lost me business). Any residue that looks like wax is purely residue from inside the beeswax candle as it burns. There is no chimney effect which can draw wax up from your ear canal and into the candle. The warm air that circulates the ear, nose and throat canal though can help soften wax and relieve mucus.
Do a little test - burn a candle on its own in a glass, open up the candle and you may well still find residue inside - candle residue.
As I understand it a previous ear candle thread opened a right old can of worms - with believers and non-believers - and eventually the thread went on that long it was shut down.
Hope this helps.
